ARTICLE II

AGREEMENT

NOW THEREFORE, in consideration of the covenants, conditions and agreements hereinafter set forth, and for other good and valuable consideration, the receipt and adequacy of which are all hereby acknowledged, the parties hereto covenant and agree as follows:

Section 1.               Amendments to the Credit Agreement.  The Credit Agreement is hereby amended as follows:

(a)           Section 1.01 of the Credit Agreement is hereby amended by restating the following definitions to read in their entirety as follows:

“Applicable Rate” means, from time to time, as of any date of determination, the following percentages determined as a function of the Consolidated Leverage Ratio for the Borrower and its Subsidiaries:

1

The foregoing ratio shall be determined from the Compliance Certificate of the Borrower and its Subsidiaries most recently delivered pursuant to Section 6.02(a).  Any increase or decrease in the Applicable Rate shall be effective upon the first Business Day immediately following the date of delivery of the Compliance Certificate required by such Section; provided, however, that if a Compliance Certificate is not delivered when due in accordance with such Section, then, upon the request of the Required Lenders Pricing Level 1 shall apply, in each case as of the first Business Day after the date on which such Compliance Certificate was required to have been delivered and shall remain in effect until the date on which such Compliance Certificate is delivered.  Beginning on the First Amendment Effective Date until delivery of the Compliance Certificate for the period ending March 31, 2011, the Applicable Rate shall be at the Pricing Level associated with the Consolidated Leverage Ratio reflected on the Compliance Certificate delivered for the period ended December 31, 2010.

“Consolidated EBITDA” means, for any period, for the Borrower and its Subsidiaries on a consolidated basis, an amount equal to Consolidated Net Income for such period plus (a) the following to the extent deducted in calculating such Consolidated Net Income: (i) Consolidated Interest Charges for such period, (ii) the provision for Federal, state, local and foreign income taxes payable by the Borrower and its Subsidiaries for such period, (iii) depreciation and amortization expense, (iv) non-cash items of the Borrower and its Subsidiaries reducing such Consolidated Net Income, (v) other non-recurring items of the Borrower and its Subsidiaries reducing such Consolidated Net Income, and (vi) without duplication, the Transaction Costs properly allocated to such period, if applicable, and minus (b) the following to the extent included in calculating such Consolidated Net Income:  (i) Federal, state, local and foreign income tax credits of the Borrower and its Subsidiaries for such period and (ii) all non-cash items increasing Consolidated Net Income for such period; provided, however, notwithstanding the foregoing, (A) net income attributable to Subsidiaries that are not Guarantors shall not be considered in calculating Consolidated EBITDA, but actual cash distributions to the Borrower or any of its Subsidiaries by such Subsidiaries that are not Guarantors shall be included in calculating Consolidated EBITDA and (B) actual cash distributions to the Borrower and its Subsidiaries by any Persons that are not Subsidiaries shall be included in calculating Consolidated EBITDA.

For purposes of calculating the Consolidated Leverage Ratio, Consolidated Senior Leverage Ratio and Consolidated Interest Coverage Ratio, Consolidated EBITDA shall be calculated, on a pro forma basis, after giving effect to, without duplication, any permitted Acquisition occurring during the period commencing on the first day of such period to and including the date of such Acquisition (the “Reference Period”), as if such Acquisition occurred on the first day of the Reference Period.  In

2

making the calculation contemplated by the preceding sentence, EBITDA generated or to be generated by such acquired Person or by such acquired Property shall be determined in good faith by the Borrower based on reasonable assumptions and may take into account pro forma expenses that would have been incurred by the Borrower and its Subsidiaries in the operation of such acquired Person or acquired Property, during such period computed on the basis of personnel expenses for employees retained or to be retained by the Borrower and its Subsidiaries in the operation of such acquired Person or acquired Property and non-personnel costs and expenses incurred by the Borrower and its Subsidiaries in the operation of the Borrower’s and its Subsidiaries’ business at similarly situated facilities of the Borrower or any of its Subsidiaries; provided, however, that such pro forma calculations shall be reasonably acceptable to the Administrative Agent if the Borrower does not provide the Administrative Agent with an Approved Consultant’s Report supporting such pro forma calculations.

For purposes of calculating the Consolidated Leverage Ratio, Consolidated Senior Leverage Ratio and the Consolidated Interest Coverage Ratio, Consolidated EBITDA shall be calculated by deducting, to the extent previously included in the calculation for any relevant period, Consolidated EBITDA attributable to a particular asset subject to a Disposition prepayment required by Section 2.05(a) after giving effect to such Disposition occurring during the period commencing on the first day of such period to and including the date of such Disposition (the “Disposition Reference Period”), as if such Disposition occurred on the first day of the Disposition Reference Period.

Notwithstanding any provision of this Agreement which may otherwise be to the contrary, if any lease pursuant to the Eunice Lease Documents is treated under GAAP as a capital lease, then, for all computations of Consolidated EBITDA hereunder, such lease shall be treated as an operating lease and Consolidated Net Income, Consolidated Interest Charges, provision for Federal, state, local and foreign taxes, depreciation, amortization and other non cash items, for all purposes of determining Consolidated EBITDA under this Agreement for any period, shall be adjusted as though such lease was accounted for as an operating lease.

“Maturity Date” means May 2, 2016, provided, however, that if such date is not a Business Day, the Maturity Date shall be the next preceding Business Day.

“Material Subsidiary” shall mean a Wholly-Owned Subsidiary of the Borrower having:  either (a) 2.5% or more of consolidated EBITDA for the four fiscal quarter period ending as of the most recent fiscal quarter for which the Borrower has delivered financial statements pursuant to

3

Section 6.01(a) or (b); or (b) 1% of the book value of the consolidated assets of the Borrower and its Subsidiaries as of the end of the most recent fiscal quarter for which the Borrower has delivered financial statements pursuant to Section 6.01(a) or (b); provided, however, to the extent that executing a Guaranty would result in adverse tax consequences with respect to any non-operating Subsidiary (as reasonably determined by the Borrower), such non-operating Subsidiary shall not be considered a “Material Subsidiary” unless such non-operating Subsidiary has either (i) 5% or more of consolidated EBITDA for the four fiscal quarter period ending as of the most recent fiscal quarter for which the Borrower has delivered financial statements pursuant to Section 6.01(a) or (b) or (ii) 5% or more of the book value of the consolidated assets of the Borrower and its Subsidiaries as of the end of the most recent fiscal quarter for which the Borrower has delivered financial statements pursuant to Section 6.01(a) or (b).

“Swap Contract” means (a) any and all rate swap transactions, basis swaps, credit derivative transactions, forward rate transactions, commodity swaps, commodity options, forward commodity contracts, equity or equity index swaps or options, bond or bond price or bond index swaps or options or forward bond or forward bond price or forward bond index transactions, interest rate options, forward foreign exchange transactions, cap transactions, floor transactions, collar transactions, currency swap transactions, cross-currency rate swap transactions, currency options, spot contracts, or any other similar transactions or any combination of any of the foregoing (including any options to enter into any of the foregoing), whether or not any such transaction is governed by or subject to any master agreement, and (b) any and all transactions of any kind, including physical trades of Hydrocarbons, and the related confirmations, which are subject to the terms and conditions of, or governed by, any form of master agreement published by the International Swaps and Derivatives Association, Inc. or the North American Energy Standards Board, any International Foreign Exchange Master Agreement, or any other master agreement (any such master agreement, together with any related schedules, a “Master Agreement”), including any such obligations or liabilities under any Master Agreement.

“Threshold Amount” means $30,000,000.

“Transaction Costs” means all (a) upfront, original issue discount, legal, professional and advisory fees paid by the Borrower (whether or not incurred by the Borrower) in connection with the negotiation and execution, delivery and performance of the Borrower’s obligations under (i) this Agreement (including any amendments, supplements or restatements), (ii) the Indenture (and the Borrower’s issuance of Indebtedness governed thereby) and (iii) the 2010 Equity Issuance, (b) payments made by the Borrower to any counterparty to any Swap Contract

4

in connection with the termination of such Swap Contract as a result of the transactions contemplated by this Agreement (including any amendments, supplements or restatements) and the Indenture, and (c) make-whole amounts, prepayment premiums and interest paid in kind with respect to Indebtedness prepaid on or before the Closing Date with the proceeds of the Indebtedness incurred pursuant to this Agreement and the Indenture.

(d)           Section 5.06(b) of the Credit Agreement is hereby restated in its entirety to read as follows:

(e)           Section 6.12 of the Credit Agreement is hereby restated in its entirety to read as follows:

6.12         Additional Material Subsidiaries; Additional Security.  (a) Upon the formation or Acquisition of any new direct or indirect Material Subsidiary (including any Subsidiary that becomes a Material Subsidiary) by any Loan Party, then the Borrower shall, at the Borrower’s expense:

(i)            subject to subsection (c) below, within 30 Business Days (or such longer period as permitted by the Administrative Agent in its sole discretion) after such formation or Acquisition or such Subsidiary becoming a Material Subsidiary, cause such Subsidiary to duly execute and deliver to the Administrative Agent a supplement to the Guaranty substantially in the form attached thereto;

(ii)           subject to subsection (c) below, within 30 Business Days (or such longer period as permitted by the Administrative Agent in its sole discretion) after such formation or Acquisition or such Subsidiary becoming a Material Subsidiary, cause such Subsidiary to duly execute and deliver to the Administrative Agent Collateral Documents, as specified by and in form and substance reasonably satisfactory to the Administrative Agent securing payment of all the Secured Obligations of such Subsidiary under the Loan Documents; and

(iii)          within 30 Business Days (or such longer period as permitted by the Administrative Agent in its sole discretion) after such formation or Acquisition or such Subsidiary becoming a Material Subsidiary, cause, subject to subsection (c) below, 100% of the Equity Interests of each such Subsidiary owned by the Borrower or a Guarantor to be subject to a first priority, perfected Lien (subject only to Permitted Liens) in favor of the Administrative Agent pursuant to the terms and conditions of the Collateral Documents.

(i)            Section 7.07 of the Credit Agreement is hereby restated in its entirety to read as follows:

Engage in any business other than a Permitted Business, except to such extent as would not be material to the Borrower and its Subsidiaries taken as a whole.
